It does. We also evolved embryo wasting. A measurement to reduce non-viable pregnancies. Except it also tends to dispose of potentially healthy embryo's. They used to think 70% was wasted. But now they think it's between 40 and 60%.

This is a good thing, since it also enables more monogamous behaviour. More sex with the same guy = greater chance at conception. And reduces both male/male and female/female competition. So basically more coop-mode for everyone. Sucks only women suffer the drawbacks of this perk.

Not only that. Paternal care is something other primates lack. But men did develop paternal care as prolactin levels in the brain increase when men see their baby. Paternal care interestinly enough, isn't just a back-up parent in case the mom dies during labour. It's invaluable. Especially to boys who prefer to learn from their fathers.

On top of this, we also have meno- and andropause. Where people lose fertility. This is only seen in two other species. Both matriarchies where the leader is determined by her experience. Orca's and elephants. Sticking around while not competing with her own children is amazing. It's why we live so long. Fun fact. Male orcas only live 30 years, but female orcas live somewhere between 60 and 90 years. Makes that "women live 3 years longer than men on average" seem insignificant huh? In any case. Love your grandparents.

Anyhow. It's no surprise that forced mating is so common in nature, but not that common in humans. We are doing well despite rape still existing.

The main reason men drop out of becomming an elementary teacher, is because they have to work parttime at a kindergarten for 6 months. Most of them want to teach, not care for walking shit/vomit fountains.

It would make sense. There are other behaviours that directly lower male aggression. Smiling and emotional tears.

Which is awesome for babies since non-human primate males are known to kill offspring of other males in order to get the mother in estrus sooner.

It's also the reason women smile when nervous and cry a lot more. I suppose you have to if you lack offense and defence. E.g. estrogens slowing muscular and skeletal growth in the upper body. And growing hair enough for thermal regulation, but not enough to redistribute blunt forces. The reason beards exist is to protect the jaw.

Interestingly, the main motive for men to commit homicide is dominance seeking behaviour. Men are more likely to kill every age with exception of infants. Women's main motives for homicide are self-defence first and jelousy second. Infanticide is almost exclusively done by women. Often their own too. Never trust a woman who had a miscarriage with your newborn or your pregnant wife. High prolactin, loss of child and stealing babies is not just a human thing.

I wonder how the willingness to kill your own (high risk and expensive) baby influenced human evolution. Since it's the other way around in other primates. Recon it reduced rape to be merely a dominance thing rather than a reproductive strategy?

Yeah. Control, control and more control. It's no suprise women are getting sterilised.

Not to mention how much of a life saver the pill is for women with dismenorrhea.

Does he? I suppose he does. Being an economist on the counterweight continent.

I love discworld. I don't get the quote though. Anything you wanna add op?

[-] Shou@lemmy.world 3 points 2 days ago

Tell em that. Let them research that too.

They are already trying to ban contraceptives. Cancer is what they are.

Not just that, it eliminates power and influence from women too. More drop outs, and more discrimination in job interviews.

Well? Now's a good time.

[-] Shou@lemmy.world 9 points 2 days ago

Yup. Makes me feel calm and focussed. Even though it physically causes my heartrate and bloodpressure to increase. Sometimes till discomfort. Worth the work focus though.

I had cats my whole life and never had this happen.
